Product Description

2 µm Filter Wavelength Division Multiplexer

(GK-FWDM Series)

Description

The GKER Photonics 2 µm Filter Wavelength Division Multiplexer (GK-FWDM Series) is a high-performance optical
device designed to facilitate efficient wavelength division multiplexing (WDM) in advanced fiber-optic systems.
Leveraging cutting-edge thin-film filter technology, this multiplexer excels in combining or separating light across a wide
range of wavelengths with unparalleled precision.
The 2 µm Filter Wavelength Division Multiplexer series is based on environmentally stable thin-film filter technology. The
devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss,
low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be
achieved through unique pigtail processing and high quality AR coating.

Specifications
¹IL is 0.3 dB higher, RL is 5 dB lower for each connector added.
